title: Distal unlocked proximal femoral intramedullary nailing for intertrochanteric femur fractures.
abstract: We investigated whether a proximal femoral nail (PFN) having two lag screws can be implanted without distal locking screws in AO/OTA 31-A1 and 31-A2 intertrochanteric femur fractures. Twenty-four patients with AO/OTA 31-A1 and 31-A2 fractures were treated with a PFN without distal interlocking by a single surgeon. The mean follow-up was 12 months (range: 7-23). Clinical and functional outcome was assessed according to the Harris hip score and Barthel's activity score. The fractures healed in all patients; the average consolidation time was 14 weeks (range: 9-28). Fourteen patients had excellent and good results, nine patients had fair results, and one patient had a poor result according to the Harris hip score; 17 patients had a high range of mobility according to the Barthel activity score. Our results suggested that the PFN can be successfully implanted without distal interlocking in 31-A1 and 31-A2 fractures.
